6203.33.10 - Containing 36 percent or more by weight of wool or fine animal hair

This HTS code encompasses suit-type jackets and blazers specifically manufactured for men and boys, where the primary material composition is synthetic fibers. The defining characteristic of this classification is that the garment contains 36 percent or more by weight of wool or fine animal hair, intermingled with synthetic fibers. This material blend is crucial for distinguishing these garments from others within the same chapter.

Within the category for suit-type jackets and blazers of synthetic fibers, this particular HTS code is distinct from sibling category 6203.33.20. While both pertain to synthetic fiber jackets and blazers, this code specifically addresses those with a significant wool or fine animal hair content (36% or more by weight). Category 6203.33.20, conversely, would cover similar garments made predominantly of synthetic fibers with a lesser or negligible amount of wool or fine animal hair.

This classification further subdivides based on the intended wearer, differentiating between garments designed for men and those specifically tailored for boys. This distinction is important for accurate inventory management and adherence to specific import regulations that may vary based on the target demographic for the apparel.
